What is the value of x in the equation x y 30 when y 15?
If you mean: x+y = 30 and the value of y is 15 then the value of x is also 15
What is the answer Y and x have a proportional relationship and y 15 when x 3. What is the value of x when y 4?
x is 0.8
What is the value of x in the equation x and ndash y 30 when y 15?
x is 45.
What is the x value 2x-3y equals -15 x equals 4y?
If: 2x-3y = -15 and x = 4y Then: x = -12 and y = -3
Use addition or substitution to find the value of x for this set of equations for x - y equals 120 x plus y equals 150?
X = 135 and y = 15 Solved by addition and substitution

Does there have to be an x value and a y value in a word problem?
Given that it does not change directly with x, and it is y = 15 when x = 5, find the value ofi y at x = 7
X+y=15?
x+y=15 or y=x-15 x=-y+15 or you could graph and get (0,15) and (15,0) and thats it
What is y equals 5x-15 if x equals1?
If y equals 5x-15 and x equals 1 then the value of y comes out to be -10. So y equals 5x-15 is -10.
If y equals 5 when x equals 4 what is the value of y when x equals 12?
13 ? 15
Given y is inversely proportional to x If the difference in the values of y when x 2 and x 6 is 5 How do i find the value of y when x 4?
As y is inversely proportional to x, the equation relating x to y is given by: y = k/x where k is the constant of proportionality. Using this we can find expressions for the value of y when x = 2 and x = 6 in terms of k: x = 2 → y = k/2 x = 6 → y = k/6 The difference between these is k/2 - k/6 = 3k/6 - k/6 = 2k/6 = k/3 But this, we are told is 5; thus: k/3 = 5 → k = 15 Thus y = 15/x Now that we have found the equation relating x to y, we can plug in the value for x = 4 and find the value of y: The value for y when x = 4 is y = 15/4 = 3.75
What does x - y?
In expressions such as "x-y", both "x" and "y" can have any value. The value of "x-y" will depend on what the value of "x" and the value of "y" are.
